UNITED STATES' PATENT OFFICE.

IMPROVEMENT IN FOLDING CHAIRS.

Specification forming part of Letters Patent No. 80,656, datedv A ugust 4, ISGS.

To @ZZ whom t may concern.-

Beit known that I, J. NIooLAI, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and Improved Folding Chair; and Ido hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to a new and useful improvement on a folding chair, for which Letters Patent were granted to me bearing date November 19, 1867.

rllhe present improvement consists in connecting the legs and seat of the chair in such a mannerv that said parts will move simultaneously in folding and unfolding the chair, thereby rendering the chair capable of being adjusted (folded and unfolded) with far great-er facility than hitherto. A

In the accompanying sheet of drawings, Figure l is a side sectional view of my invention in an unfolded state; Fig. 2, a front view of the same ina folded state.

Similar letters of reference indicate corresponding parts.

A A and B B represent the legs of the chair, which cross each other at each side and are connected by pins or pivots a. The legs B eX- tend upward a requisite distance, are connected by a cross-bar, b, at their upper ends, and form the back of the chair.

C represents the chair-seat, the "rear part of which is secured by pivots c c between the legs B B, some distance above the pivots a.

To the under side of the seat C, at or near l each side thereof, there is secured a rod, d, on each of whicha ring, e,'is fitted and allowed to slide or move freely back and forth.

To the upper parts ofthe legs A A thereis attached a bar, D, which passes through the rings c e, and by means of the rings e, rods d d, and bar D a connection is formed between the scat C and the legs A A, so that by moving either leg A or the seat O the chair may be folded or unfolded, all the parts moving simultaneously.

To the under side of the front part of the seat (l there are attached legs f f, to serve as steps for the bar Dwhen the chair is unfolded. By this arrangement I am enabled `to dispense with all straps and arms to hold the parts in position when in an unfolded state.

Iwould remark that I prefer to h ave the bar as shown in the drawings, as this admits of the parts being folded together more coinpactly than they otherwise could be.

claim as new, and desire to secure by Letters Patent, is-

l. A folding chair having its seat C andlegs A A connected by the bar D, rings e e, and guide-rods d d, all arranged substantially in the manner as and for the purpose set forth.

2. The legs or steps ff, attached to the seat C, in combination with the bar D, rings e e, and guide-rods d d, for the purpose specified.
